Chromosome tightly coiled molecule of dna that is partly covered by: if dna in one human cell were stretched out it would be 2m long. Genes carry the hereditary blueprint of a portion of dna limitations: carry information for your characteristics, potentials, and, code for proteins which affect body development and function, half of genes target brain structure/activity. Zygote formed when two haploid cells fuse during conception (23 chromosomes from each parent cell to from 46 chromosome zygote: offspring receives one gene pair from each parent. Alleles alternative forms of a gene containing different characteristics. Recessive gene characteristic is not expressed, unless its matched against another recessive gene: recessive genes can still be passed to offspring who may display the recessive gene.
